For the quantum number lower case L = 0, how many possible values are there for the quantum number m subscrip l?
hram777 [196]
Quantum number L, angular quantum number, describes the shape of the orbitals. Reliable sources show that the quantum number l = 0 will give an orbital of spherical shape, polar if l = 1, and cloverleaf if l = 2.

The third quantum number is m which is is used to denote the magnetic quantum number. This describes the orientation of a certain orbital in shape. This quantum number can take the values of -l to l. Thus, the only value for m in this case is 0. m = 0.  

Quantum numbers are used to describe the position of the electrons in the orbitals.

If a sample contains 100.0 g of lead atoms (Pb), how many atoms are present in the sample?
Igoryamba

Answer:

The answer to your question is the letter C. 2.906 x 10²³ atoms

Explanation:

Data

mass of Lead = 100 g

The Number of atoms = ?

Process

1.- Look for the atomic number of Lead in the periodic table

Atomic number = 207.2 g

2.- Use proportions and the Avogadro's number to calculate the number of atoms.

                      207.2 g ------------------ 6.023 x 10²³ atoms

                       100 g    -----------------   x

                       x = (100 x 6.023 x 10²³) / 207.2

                       x = 6.025 x 10²⁵ / 207.2

                      x = 2.906 x 10²³ atoms

]If a sample of pure iodine contains 4.69 x 1022 atoms of iodine, how many moles of iodine are in the sample? A=0.08 B=0.13 C=7.
Lorico [155]
It is B, and also for a moment I didn't understand that 4.69 x 10^22. I almost did this whole problem wrong.
